ROLLER-BEARING.

Application filed April 12, 1920. Serial No. 373,354.

Pennsylvania, have invented certain new and useful Improvements in Roller-Bearings, of which the following is a specification.

My invention relates to improvementsin bearings. An important object of the invention is to provide a device of the above mentioned character, formed of few and simple parts which are held together in a positive manner.

A further object of the invention is to provide means for lubricating the contacting elements of the hearing, such means being adapted to permit of the use of the bearing.

in diiferent angular positions.

A further object of the invention is to provide a bearing which is highly efficient and reliable in use.

Other objects and advantages of the invention will be apparent during the course of the following description.

In, the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same- I Figure 1 is a central vertical transverse section taken through a bearing embodying my invention,

Fig. 2 is a central vertical longitudinal section taken through the same,

Fig. 3 is a perspective view of the engagingi ends of the inner casing of the device, an

Fig. 4 is a side elevation of the bearing, vertically arranged.

In the drawings, wherein for. the purpose of illustration are shown preferred embodie ments of my invention, the numeral 5 designates a base element or block, included in the outer box. This base element is provided with a transverse recess 6, which is semicylindrical. The element 5 has inwardly projecting flanges 7, at the ends of the recess 6, as clearly shown in Fig. 1. y

The numeral 8 designates an outer or cap element, the inner portion of which is longitudinally curved and provided with a transverse semi-cylindrical recess 9, to register -With the recess 6. The cap 8 has inwardly extending flanges 10, at the ends of the re- Specification of Letters Patent.

11, Fig. 2, which extend inwardly to be in alinement with the center of the recess 9. These sockets receive the projections or flanges 12, included in the element or block 5. It is thus apparent that the cap and block are securely interlocked, interiorly, adjacent their recesses. The cap 8 is continued longitudinally in the form of straight bars 13, having their ,outer ends 14; preferably slightly beveled, to engage within outwardly extending flanges 15, formed upon the ends of straight bars 16, included in the block 5, as shown. It is obvious that the bars 13 and 16 are securely interlocked.

The bars 13 and 16 are provided with transverse openings 17, preferably 1 at each end of the device, and these openings receive having a tongue 21, and the other end a groove 22, as clearly shown in F 1g. 3. The

inner casing may be formed of a different metal from the block, if desired, such as brass or the like. Theinner casing is arranged within the recesses 6 and 9, and their engagingends are disposed to'break joint with the ends of the projections or flanges 12. as shown. I

Extending. centrally through the inner casing is the shaft 23, to be supported, which engages rollers or rolling elements 24, contacting with the interior of the inner casing, and held against longitudinal displacement by the flanges 7. These rollers are a suitable size so that they Will not bind, upon their expansion, should the bearing become heated. a y

Mleans is provided to retain the bearing suitably lubricated, and for this purpose I employ a cup 25, forrholding a lubricant. This cup has a cap 26, apertured at 27 The cap 25 has a tubular extension 28, screwthreaded into an opening 29, in the cap, and this tubular extension is in registration with an opening 30, formed in the casing-section 20, as shown. The cap 8 is provided with a second screw-threaded opening 31, preferably'arranged 45 from the opening 29. and of the same diameter. The opening 31 is adapted to receive the tubular extension 28,

I when the bearing is vertically arranged, as

- including longitudinal bars arranged upon,

shown in Fig. 4:. The numeral 32 designates a locking plug, serving to close either of the openings 29 and 31, and will clamp against the inner casing, preventing turning movement thereof, so that the opening 30 may be retained in registration with the bore of the tubular extension 28, when inserted within either screw-threaded opening.

The bearing may be horizontally arranged, as shown in Fig. 2,. or vertically disposed, as shown in Flg. 4, in each case the base and cap being securely locked together, the inner casing clamped against turning movement, and the lubricant prop erly fed to the contacting elements.

It is to be understood that the form of my invention herewith shown and-described is to be taken as a preferred example of the same, and that various changes in the shape,

size, and arrangementof parts' may be resorted to Without departing from the spirit of my invention, or the joined claims.

Havingv thus claim:

1. A. hearing adapted to be used in substantially horizontal and vertical positions, comprising a base element provided upon its outer side with a recess, said base element scope of the subdescribed my invention, 1

opposite sides of the recess, a cap provided with an interior recess to coact with the first named recess, said cap having a pair of screw-threaded openings which are circumferentially spaced, said cap being provided at its ends with longitudinal bars, means to secure the sets of bars together, a lubricating device having a tubular screw-threaded extension tobe screw-threaded into eitherscreW-threaded opening, an inner casing within the recesses having an opening formed in its penphery to register with either screw-threaded opening, and a clamping plug to engage within either screwthreaded opening for holding the inner casing against turning movement.

2. n a. bearingot the character described,

freeware a block having a recess and laterally extending projections upon opposite sides of the recess, said block including longitudinal bars extending from the projections, a cap having a recess and interior sockets to receive the projections, said cap having longitudinal bars to engage with thefirst named bars, said cap also having a pair of screwthreaded openings which are circumferentially spaced, an inner casing disposed with-' in the recesses and includin cas ng-sections having engaging ends, sai engaglng ends being disposed to break joint with the ends of the projections, one casing-section having an opening for communication with either screw-threaded opening, a lubricating device having a tubular screw-threaded extension to be screw-threaded into either screwthreaded opening, a clamping plug to be screw-threaded into either screw-threaded opening to close the same and lock the casing against turning movement, and rotatable are disposed to break-joint with the ends of 'the flanges, one casing-section having an opening for communication with either screw-threaded opening, a lubricating de vice having a tubular screw-threaded .extension to engage ineither screw-threaded opening, a screw-threaded clamp-ing plug to engage either screw-threaded opening and hold the casing against turning'movement, and rolling elements within the casing.

In testimony whereof I afliX my signature in presence of two witnesses.
